SPOKE-TIGHTENING DEVICE.

Specification of Letters Patent.

Application filed February 26, 1909. Serial No. 480,170.

To all whom it may concern:

Be it known that I, Rnmnonn Weren- MANN, a citizen of the United States, res1ding at Houston, in the county of Harris and State of Texas, have invented certa1n new and useful Improvements in Spoke-Tightcning Devices, of which the following 15 n specification.

My invention relates to new and useful improvements m spoke tightening (lBViCBS and more particularly to that class of such devices as are designed to be used on the spokes of such vehicles as wagons and buges. The device is designed to fit on the end of the spoke and forms a part thereof and is provided with means for fastening the spoke to the folly as well as means for lengthening and shortening the spoke.

The object of the invention is to provide a device of the character described whereby as to keep the folly drawn tight against the tire in order to keep the wheel firm and substantial.

Another object resides in the provision of means whereby a broken or injured spoke may be removed and replaced without the necessity of removing the tire and felly or taking the wheel apart.

Finally the object of the invention is to provide a device of the character described that will be strong and durable; one which will be simple and inexpensive to construct and one in which the parts will not be liable to et out of working order.

\Tith the above and other objects in view my invention has particular relation to certain novel features of construction and operation an example of which is described in thisspeoification and illustrated in the ac companying drawings wherein Figure 1, is a side elevation of a section of a wheel showing my device in elevation. 5 Fig. 2. is an enlarged elcvationul view of 1 the device, F i 3,is a transverse vertical sectional view t icrcof.

Referring now more mrliculzu'ly to the drawings wherein like munemls of rotorcncc desi mate similar parts in each of the figures, dhe numeral 1. refers to a. clamp adapted to embrace the folly, as shown. and )rovided with apertures 2, for rncciving olts, which are designed to pass through l I l l the said apertures and the telly for holding said clamp in its proper position. This clamp is provided with a centrally located, inwardly extending, nipple 3 which is surrounded by a circular groove 4. This nippie is adapted to project into an intermediate sleeve 5 which is provided with a recess for its reception. The sleeve also carries a circular flange upon its outward and which is adapted to fit into the groove at and the connection between the clamp 1 and sleeve 5 is thereby strengthened, and the sleeve is also thereby permitted to turn when it is desired to lengthen or shorten the spoke. The sleeve also carries a collar 6 near its outward end which is integral with said sleeve and which is adapted to ,rest firmly against clamp 1 and thereby further strengthen the said connection.

The numeral 7 refers to a ferrule which preferably, conical in shape, and which is adapted to receive the outward end of the spoke proper. This ferrule carries a threaded extension 8 which is adapted to screw into a tapped hole in the inward end of sleeve 5.

The sleeve 5 carries a polygonal head 9 by means of which it may be turned with a wrench. The extension 8 is connected to the ferrule proper by means of a neck 10, smaller in diameter than the main extension, over which the sleeve 5 may pass when the spoke is being shortened and thus greater latitude is given in lengthening and shortening the spoke.

It is believed that from the above description the method of o eration of this device will be readily un erst-ood without further explanation; but I desire to reserve the rightto vary the specific form and con- :51 motion shown and described so long as the spirit. of the invention is not departed from.
